Abstract
Embodiments described herein relate to a system and method for improving a rate of success in receiving response packets, such as 802.11 Acknowledge (ACK), Block Acknowledge (BACK), and Clear-To-Send (CTS) packets. In one embodiment, a wireless device may transmit one or more first packets according to a wireless communication protocol, and may then receive a second packet. The wireless device may determine that the receiving follows the transmitting by a specific duration of time that is specified by the wireless communication protocol for a response packet to follow one or more communication packets to which it responds. Based at least in part on this determining, the wireless device may further determine that the second packet is a response packet responding to the one or more first packets, without decoding a portion of the second packet that identifies a packet type of the second packet.
